Nearsightedness and Farsightedness
(Myopia and Hyperopia)
|Copyright © Nucleus Medical Media, Inc.|
- Age: 40 or older (hyperopia due to presbyopia )
- Family member with hyperopia
- Blurred vision of distant objects
- Blurred vision of close and often distant objects
- Need for more light while working
- Eye fatigue
- Soft contact lenses
- Laser in situ keratomileusis (LASIK) —the use of a laser to permanently reshape the cornea by etching away cells beneath its surface (the most common surgical treatment for myopia)
- Laser epithelial keratomileusis (LASEK)—a procedure that is quite similar to LASIK, but differs in a technique of removal of the first layer of cornea. LASEK supposedly offers benefits over the typical LASIK procedure in terms of faster healing time and decreased post-surgical pain. Those benefits have been however questioned by recent studies. More research is needed to clarify the benefits of the LASEK procedure.
- Epi LASIK procedure (Epithelial laser-assisted in situ keratomileusis )—a hybrid procedure that combines elements of both LASEK and LASIK.
- Photorefractive keratectomy (PRK)—the use of a laser to permanently reshape the cornea by removing cells on its surface (less commonly done)
- Radial keratotomy (RK)—the use of microincisions to flatten the cornea (rarely done)
- Intraocular lenses—in some situations, removing your native lens and possibly replacing it with an intraocular lens can help treat myopia
- Under- and over-correction
- Visual problems such as glare or double vision
- Dry eyes
- Post-surgical problems with healing and/or infections
- Long-term complications (more than 10 years of follow-up) are unknown at this time
